SISTAR is back and ready to heat up the summer with their Summer Special Album, 'LOVING U'!Debuting in 2010 with 'Push Push', the group caught and maintained the public attention with the following singles, 'Ma boy (SISTAR19)', 'How dare you', 'SO COOL', and finally ranked No.1 with their 1st Mini Album 'Alone'. The girls' new track, 'Loving U', shows off the sexy and cute charm of the girls with the combinations of acoustics and synths. Produced by Duble Sidekick (Double Sidekick), the album contains SISTAR's new tracks 'Loving U' and 'Holiday' and also their top hit tracks that have been reborn with collaborating with Korea's representative electronic music label, Foundation Records.Utilizing visuals such as 'marine looks' and 'vacance looks' in bright summer colors, the girls are going to shed their original image and go for something cuter and brighter.The entire video was shot in Hawaii by JOO Heesun, the top music video director who worked for Son Dam Bi's 'Crazy', Afterschool's 'Bang', and SISTAR's 'Alone'.
